Is the availability of solar power, and the low energy need to run basic wi-fi
But one needs long-term trials showing survivability during storms and inclement weather events, as well as impacts on aviation due to mobile wi-fi.
The main design choice is between mobile wi-fi repeater platforms that communicate with satellites for a period of time, and ones that have a fairly long lifespan (2-3 years) and are mobile to locate at a specific region. If you keep things up in the air, stuff happens to them. In the New Zealand trials in remote areas, the lifespan was a bit short, so the cost per day of service depends on the weather.
